Cl
• Two or more atoms bonded (attached) (chemical forces)
• Smallest unit of any compound that keeps the properties of that compound.
Covalent Bond
• A pure substance • A substance made up of
atoms from two or more bonded elements.
Ionic Bond
• A combination of two or more substances blended together
• No set ratio of ingredients
• Homogeneous: 2 or more things evenly blended and disappear into each other.
• Solute – Smaller quantity• Solvent – Larger quantity• Solution – a homogeneous
mixture
• Heterogeneous: 2 or more things put together and still can be seen.
• No set RATIO.
• We know the definition of Element, Compounds & Mixtures
• What do their particles look like?
Compound

Mixture
Element
Compound
Can you create your own?
• 2 different samples of Elements• 2 different samples of Compounds• 2 different samples of Mixtures
1. Mixture of Elements, 2. Mixture of Compounds or 3. Mixture of Elements and Compounds
• Materials Managers: Pick up one supply bag for your table
• Separate and Layout 6 small zip lock bags labeled, ELEMENT, COMPOUND, MIXTURE, Supplies
• Build: A 2 examples of each
• Your table should have:– 2 diff. examples of Element
Particles– 2 diff. examples of Compound
Particles– 2 diff. examples of Mixtures
• Mixture of Elements• Mixture of Compounds• Mixture of Elements and Compounds
– Get a Signature from Mrs. M.
• Complete Venn Diagram ONLY – We will finish the rest in class tomorrow – Due by the end of the period tomorrow
• Correct Test #3 and Get Signed – Due tomorrow
